You pick it: AFC West story lines

The candidate are:

Denver trades skill-position players: The Broncos sent Pro Bowl receiver Brandon Marshall to Miami and tight end Tony Scheffler to Detroit for draft picks.

Gradkowski hurt: Oakland quarterback Bruce Gradkowski suffered a pectoral tear while lifting weights last week. He is expected to be ready by training camp. Oakland signed former first-round pick Kyle Boller the day after Gradkowski was hurt.

Denver studies Tebow: The Broncos brought Florida quarterback Tim Tebow to their facility Wednesday and then worked him out Monday.
